COTTON-GIN RIB,

Application filed November 10, 1927. Serial No. 232,384.

This invention relates'to improvements in cotton gin and'linter breasts.

An object of this invention isto provide an improved cotton gin rib which may be held in position by a supporting element'located at the bottom of the breast and ardium of a sliding clamp device at the-top of the breast thereby greatly facilitating and simplifying the assembling of the gin breast or grate fall at the factory or in the gin house. The rib according to this invention may be used in place of the ordinary type of rib held in position by aplurality of wood screws adapted to fasten the rib at the top and bottom of the wooden rails. 'Another object of this inventionis to, providean improved gin rib constructed in such a manner as to insure positively proper spacing and setting of the ribs in order that the saws commonly used in cotton gins can be positioned accurately in the relationship to the ribs 7 i a The improved gin rib according to this invention is constructed to avoid the necessity of shimming at the top and bottomof the rib in orderto make it conform to positive alignment and at the same time to insure-a uniform width for all the rib elements and the maintenance of the proper center for the saws thereby making the breast interchangeable as may be desired;

Other objects of this invention are to provide an improved screwless gin andclinter breast which will eliminate the necessity of skilled labor for building up'or assembling its different elements, and to avoid the use of all screws or other similar fastening devices in the gin rib, also to eliminatethe need'of training each rib on the rib'rails so that the saws will not strike, as is the case with the old and common structure now in use. This inven-' tion is adaptable on'any make of gin or linter owing to the factthat the to conform with the standard rib of any particular apparatus. The parts may be easily replaced case of broken or worn parts, and are accurately milled by machinerytherefore making the sections interchangeable;

Other objects of this invention will appear from the followingv detailed description of the device and as disclosed in the single sheet of drawings which is herewith made apart of this application.

' of rib portions,

In operation this inventionprovides a very,

eflicient gin and linter breast particularly in the matter of the gin'ribs and huller ribs which are held in interlocked relation with the top and lower rib'rails without the use of screws or fastening elements in-the gin rib themselves. It is now the common practice to use anywhere from three rib and inasmuch as there are 81 ribs more orless to each gin breast and 101 ribs to each linter breast it can be readily perceived that a great saving in time, labor and expense has been. brought about through this invention. It is also a very simple matter with the gin ribs constructed and arranged according with this i'nventionto assemble or buildup the gin to four screws in each that the saws when a center of space between the ribs will run without striking ribs and will be interchangeable. Furthermorethe assembling may be easily done by unskilled labor as the ri s according to this invention" are merely set in place on the rib rails, and are held theresecurely by a clamp bar whereas the old device required that each rib be fastened to the topan'd bottom rib rails. The gin and linter breast according to this invention may be used on any make of gin or linter by merely constructing the curve or shape of therib to coniormwith the standard rib of the particular gin or siderationn Furthermore broken or worn ribs may be easily replaced with new ones without damaging or inconvenience in dismantling. i p
